Consolidate 5 application tools into unified search_applications
- Consolidate list_all_applications, list_applications_with_name, get_applications_by_tag, get_applications_by_metadata, and get_applications_by_metadata_name into single search_applications tool - Add 4 optional filter parameters: name, tag, metadataName, metadataValue - Implement parameter validation (error if metadataValue without metadataName) - Update cache TTL from 10 to 5 minutes - Document cache behavior (5-minute TTL) in tool description - Document tag case-sensitivity in parameter description - Add comprehensive unit tests for search_applications - All 248 tests pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Search applications with optional filters. Returns all applications if no filters specified.

Filtering behavior:

- name: Partial, case-insensitive matching (finds "app" in "MyApp")
514+
- tag: Exact, case-sensitive matching (CASE-SENSITIVE - 'Production' != 'production')
515+
- metadataName + metadataValue: Exact, case-insensitive matching for both

- metadataName only: Returns apps with that metadata field (any value)

Note: Application data is cached for 5 minutes. If you recently created/modified

applications in TeamServer and don't see changes, wait 5 minutes and retry.
